ns of E. coli, L. innocua, S. Enteritidis, and S. aureus by 1.75, 1.27, 1.39 e 1.21 log CFU/g, respectively. In addition, the populations of E. coli and S. Enteritidis were reduced by over 2 log CFU/g using US treatment. Significant reduction of all bacteria was reached after 20 min by UV light and after 30 min by US treatment.
In strawberries, the UV treatment was less effective than US because UV reduced bacteria only by 1-1.4 log CFU/g, while US reduced the population of E. coli, S. aureus,
